What is cryptanalysis?
Saturday, 10 August 2024 by Emmanuel Udofia
Cryptanalysis is the study and practice of analyzing information systems to understand hidden aspects of the systems. In the realm of cybersecurity, cryptanalysis specifically refers to the process of deciphering encrypted data without knowledge of the key used in the encryption process. This field is a important aspect of cryptography, which is the broader science
With an attack on a single LFSR is it possible to encounter combination of encrypted and decrypted part of the transmission of length 2m from which it is not possible to build solvable linear equations system?

In the field of classical cryptography, stream ciphers play a significant role in securing data transmission. One commonly used component in stream ciphers is the linear feedback shift register (LFSR), which generates a pseudorandom sequence of bits. However, it is important to analyze the security of stream ciphers to ensure that they are resistant to
